Abstract

In the present study, a mathematical model has been developed & simulated in MATLAB to determine the effect of abrasive size on total polishing time while polishing SS304 steel. The mathematical model studies the effect of two strategies on polishing time: Constant Abrasive-size Polishing Strategy (CAPS) and Variable Abrasive-size Polishing Strategy (VAPS) during polishing cycles. The theoretical results obtained from the mathematical model are compared with the experimental results. An in-house developed Pneumatically Configurable Polishing setup has been utilised, where the tool reciprocates linearly on the workpiece. The transient curves have been plotted for each strategy to determine the reduction of surface roughness with the number of passes. It is observed that VAPS significantly reduces the number of passes required to achieve desired surface finish as compared to the CAPS. It has been observed that surface roughness saturation levels are directly proportional to abrasive size with prediction errors ranging from 2 % to 16 % compared to experimental values in case of CAPS. However, VAPS leads to a 26 % reduction in total process time thus highlighting the efficiency of varying abrasive strategy in achieving a reduced polishing time.

对瞬态表面粗糙度分析的洞察：气动可配置抛光的建模和研究

在本研究中，建立了一个数学模型& &；在MATLAB中进行仿真，以确定抛光SS304钢时磨料尺寸对总抛光时间的影响。该数学模型研究了两种抛光策略对抛光时间的影响：恒磨料粒度抛光策略（CAPS）和变磨料粒度抛光策略（VAPS）。将数学模型得到的理论结果与实验结果进行了比较。内部开发的气动可配置抛光装置已被利用，其中工具在工件上线性往复。绘制了每种策略的瞬态曲线，以确定表面粗糙度随孔道数的减少。可以观察到，与CAPS相比，VAPS显着减少了达到所需表面光洁度所需的孔道数。已经观察到，表面粗糙度饱和度水平与磨料尺寸成正比，与cap的实验值相比，预测误差范围为2%至16%。然而，VAPS导致总工艺时间减少26%，从而突出了不同磨料策略在实现减少抛光时间方面的效率。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
